LOOPING-MACHINIE FOR WEB-DRIERS.

SPECIFICATION forming part of Letters Patent lilo. 592,677, dated October 26, 1897.

Application filed March 24, 1.897.

To all whom it may concern.-

I Be it known that I, LOUIS WIMMER, a citizen of the United States, residing at Elizabeth, in the county of Union and State of New Jersey, have invented certain new and useful Improvements in Looping-Machines for Paper, Oil-0loth, &c.; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make use the same, reference being had to the accompanying drawings, and' to letters of reference marked thereon, which form a part of this specification.

The object of this invention is to facilitate the operation of cooling or drying oil-cloths," wall-paper, or like fabrics which come to the machine covered with ornamental design material in a wet condition or with other coatings to be cooled, hardened, or dried, and to secure other advantages and results, some of which may be-referred to hereinafter in connection with the description of the working parts.

The invention consists in the improved machine for looping paper, cloth, &c., and carrying the same forward to the final rolls, -and thus enabling it to dry or harden prior to be being rolled onto said rolls, and in the arrangements and combinations of parts thereof, all substantially as will be hereinafter set forth, and finally embraced in the clauses of the claim.

Referring to the accompanying drawings, in which like letters of reference indicate corresponding parts in each of the figures, Figure 1 is a plan of a portion of my improved machine, and Fig. 2 is a central longitudinal and vertical section of the same. Fig. 3 is a detailed central longitudinal and vertical section of the forward end of the machine and showing modified bearings ,for the retardation-roll, and Fig. 4 is a plan of the same.

In said drawings, a indicatesthe frame of the machine,upon which the looping and carrying devices and the means for operating the same have their bearings. Said frame consists, preferably, of a series of uprights a, supported upon horizontal sills or foundation-sleepers a and supporting at or near the top of the machine parallel horizontal Serial No. 629,044. (No model.)

beams a, which last may provide bearings for certain hangers or boxes b for certain sprocket-wheels b in a series at the top of the machine. At the forward end of the machine said frame is provided with inclined braces a, providing inclined slideways a for the looping and carrying slats, or to which said slideways may be attached by means of suit III/II able supports a Said braces may serve alone or in connection with others in securing the desired firmness and'rigidity in the framework." Over the said sprocket-wheels, disposed at opposite sides of the frame, are arranged endless chains or belts o 0, having at suitable and regularintervals transverse looping' and carrying slats or bars cl, which latter move lengthwise of the frame impelled by the chains or belts c,and after receiving the looped cloth, paper, or other fabric serve in carrying said fabric while the same is drying preparatory to rolling said paper, &c., in rolls for the market.

The endless belts or chains 0 c at the sides of the machine are operated by means of sprocket-Wheels e and a shaft f, the latter receiving motion from any suitable source of power in any manner common in machinery. In connection with the said driving-shaft f is arranged another sprocket-wheel g, which is preferably smaller than the belt-operating sprocket-wheels e. Said sprocket-wheel g is in connection, by means of a belt or chain h, with another sprocket-Wheel i, mounted on a shaft 7', with afeed-roll 70, said shaft j having suitable journal-bearings on the framework at or near the top and forward end of the machine and near the inclined brace. Another roll Z is also arranged on said frame parallel with the roll it and preferably in frictional contact therewith, so that the paper is held in contact with the feed-roll and will thus be properly fed forward.

The transverse slats or bars d din their upward inclined movements pass beneath the feed-roller and enter into engagement with the under side of the paper or other fabric as the latter is fed forward by the rolls. After passing upward at the rearward side of the feed-roll said transverse slats enter into contact with, or, more properly, press, the paper against what I may calla retardation-roll ICO m, the paper being prevented thereby from being thrown an indefinite period over the upwardly-movin g transverse slat; but, on the other hand, said paper or fabric is caused immediately upon an engagement of a slat with said retardation-roll to form a new fullness and start another loop. The loops are thus regularly formed, the transverse slats or bars being correspondingly regular in arran gement. Said retardation-roll is arranged on swinging arms m, so as to admit a free passage of the transverse slat or the paper or fabric looped thereover and so that there will be no undue pressure on the paper or fabric and a consequent creasing or damaging of the same.

The loops formed by the engagement of parts and the feeding forward of the paper continue to increase in size as the slat moves upward on its inclined ways until another transverse slat enters into a similar engagement with the retardation-roll, at which time the first slat and its paper will have arrived at the horizontal series of carrying sprocketwheels I) Z) and the loops will have attained their maximum size. The series of sprocketwheels D 6' guide the chains or slat-carrying belts as they move rearwardly, so that said slats maintain a given relation to the floor for quite a long period, sufficient to allow all dampness to evaporate from the hot paper or to allow the surface covering to dry or harden or otherwise enter into a condition suitable to admit of further manipulation of the paper.

At the back or rearward end of the machine the same is provided with sprocketwheels 0 0', which guide the chain or belt in its return movements toward and over the sill, which latter provides or may provide a slideway for the slats and chain.

The feed-roll Z instead of beingoperated by friction may be more positively operated by means of intermeshing gear-wheels arranged at one end of the rolls or upon the shafts for the same.

The retardation-roll m, maintaining its effective position by gravity, may be arranged upon fixed bearings m rather than upon swin gin g arms and in that event may work in elongated slots m' in the ends of said bearings, as will be more fully understood by referring to Fig. 3.

In operating the device when the construction is that specifically described and the machine is set in motion the wall-paper, oil-eloth, or other fabric is inserted between the feedrolls 7: Z and carried downwardly and then up over the upper upwardly-moving slat, forming a short loop which rapidly increases in size, reaching its maximum size when the next slat below arrives at the retardation-roll, when a new loop is started and the first is carried rearward slowly, so that a full opportunity for drying or cooling and hardening is given the paper. Arriving at the rear end of the machine, the dried paper is taken off upon another roll ready for the market.

I am aware that various modifications may be made in the construction of my machine besides or in addition to those herein positively referred to without departing from the .spirit or scope of my invention, and I do not,

therefore, wish to be understood as limiting myself to the specific structure shown in the drawings. 7

Having thus described the invention, what I claim as new is 1. In a loopingmachine for drying or cooling paper, oil-cloth, &c., the combination with an endless chain or equivalent carrying medium having fixed transverse slats, of a retardation-roll to engage said. slats and form new loops, substantially as set forth.

2.- The combination in a looping-machine, of a slatted chain and feed-rolls arranged near the path of said chain and a retardationroll adapted to be engaged by the slats covered by the paper to serve in starting new loops, and operating means, all arranged and operating, substantially as set forth.

3. The combination in a looping-machine, with a frame having an inclined forward brace to guide, the slatted chain, sprocketwheels and feed-rolls, of a retardation-roll, arranged adjacent to said feed-roll and slatted chain, substantially as set forth.

4. The improved machine for drying paper, &c., comprising a frame embracing a sill, uprights, and horizontal beams, a horizontal series of sprocket-wheels arranged on h angers attached to said beams, feed-rolls 70, Z, a roll adapted to engage with the slats to start the loops, an endless chain carrying a series of uniformly-separated slats and means for operating said parts, substantially as set forth.

5. The improved machine for drying paper, (he. comprising a frame having at its forward end an inclined guide or way for the slats, said frame having at its upper part a series of sprocket-wheels to support the endless chain, an endless chain arranged on said sprocketwheels, means for operating said chain, feedrolls and a gravity retardation-roll adapted to be engaged by the upwardly-moving slats substantially as set forth.

In testimony that I claim the foregoing I have hereunto set my hand this 15th day of March, 1897.

LOUIS IVIMMER.
